Ingredients for Potato Soup Recipe: Creamy Cheddar Herb Fall Comfort

Exact amounts are in the printable recipe card below — here's what you'll need at a glance.

Main Ingredients

• 3 tbsp unsalted butter
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 2 lb Yukon Gold potatoes, peeled and diced 1/2 inch
• 4 cups low-sodium chicken broth
• 1 cup whole milk
• 1 cup heavy cream
• 8 oz sharp cheddar cheese, freshly grated from a block
• 1 tbsp fresh thyme leaves, chopped
• 1 tsp fresh rosemary, minced

Seasonings & Flavors

• 1 tsp kosher salt
• 1/2 tsp black pepper
• 1/2 tsp smoked paprika
• 1/4 tsp dry mustard powder

Optional Toppings

• (Optional) Crumbled cooked bacon
• (Optional) Finely sliced green onions
• (Optional) Extra shredded sharp cheddar
• (Optional) Sour cream dollop
• (Optional) Toasted crusty bread cubes

Ingredient Notes

• Yukon Gold potatoes: Best starch-to-moisture balance for creamy texture that holds shape. Russets work for thicker soup but risk gluey texture if over-mashed.
• Sharp cheddar: Must be freshly grated from a block. Pre-shredded bags have anti-caking agents that make the soup grainy and dull the melt. This is the number one failure point.
• Whole milk and heavy cream: The fat blend carries flavor and prevents dairy from separating. All half-and-half works but thins the body noticeably.
• Fresh thyme and rosemary: Add at the end so the volatile oils stay bright. Dried thyme works at 1 tsp but loses the fresh market aroma.
• Dry mustard powder: A small amount amplifies cheddar flavor without tasting mustardy. Skip it and the soup tastes flatter.

How to Make Potato Soup Recipe: Creamy Cheddar Herb Fall Comfort Step by Step

Sauté aromatics

Melt butter in a large pot or Dutch oven over medium heat. Add diced onion and cook 5–7 minutes, stirring occasionally, until translucent and fragrant. Watch for any browning past pale gold — that means the heat is too high and the soup will taste bitter.

Bloom garlic

Add minced garlic and cook 30–60 seconds until you smell it clearly. Do not let the garlic brown or it turns acrid and ruins the broth.

Simmer potatoes

Add diced potatoes, chicken broth, kosher salt, and black pepper. Bring to a simmer over medium-high, then reduce to medium-low. Simmer 18–22 minutes until a fork pierces the largest pieces easily and edges start to soften into the broth.

Mash for body

Use a potato masher to break down about half the potatoes directly in the pot. Stop when the soup looks creamy but still has visible chunks. Over-mashing turns it gluey fast.

Add dairy

Stir in whole milk and heavy cream, then return to a gentle simmer for 3–5 minutes. Do not let it boil or the dairy will separate and the soup turns grainy.

Melt cheddar off heat

Remove from heat and stir in freshly grated cheddar one handful at a time until fully melted. Add thyme, rosemary, smoked paprika, and dry mustard. Taste and adjust salt. Ladle into bowls and top as you like.

Pro Tips for the Best Potato Soup Recipe: Creamy Cheddar Herb Fall Comfort

• Ingredient prep: Dice potatoes to a uniform 1/2 inch so every piece cooks at the same rate and you avoid hard chunks alongside mush.
• Common mistake and fix: Using pre-shredded bagged cheddar is the number one failure point — anti-caking agents make the soup grainy and dull the melt. Fix: grate from a block while cold. Recovery: if already grainy, blend briefly with an immersion blender and add a splash of warm broth, but expect thinner body.
• Texture enhancement: Mash only half the potatoes for natural body while keeping tender chunks. Full mashing gives baby food; no mashing gives thin broth.
• Make-ahead and storage: Cook the soup base up to one day ahead, but hold the cheese and fresh herbs until reheat. Adding cheese early and reheating causes separation and greasiness.

Storing and Reheating Potato Soup Recipe: Creamy Cheddar Herb Fall Comfort

Refrigerator Storage

Store in an airtight glass container up to 4 days. Press plastic wrap against the surface to prevent a skin from forming.

Freezing Potato Soup Recipe: Creamy Cheddar Herb Fall Comfort

Freeze in a freezer-safe container with 1 inch of headspace for up to 2 months. Dairy may separate on thaw; stir vigorously while reheating.

Reheating in the Oven

Pour into an oven-safe dish, cover with foil, and warm at 300°F for 25–30 minutes, stirring halfway. Add a splash of broth to loosen before serving.

Reheating in the Microwave

Heat at 70% power in 1-minute bursts, stirring each time, for 2–3 minutes total. Add a splash of milk to prevent thickening and sogginess.

Make Ahead

Prep onion, garlic, and herbs up to 2 days ahead. Cook the soup base up to 1 day ahead. Hold cheese and fresh herbs until you reheat.

Frequently Asked Questions about Potato Soup Recipe: Creamy Cheddar Herb Fall Comfort

Can I make potato soup ahead of time?

Yes, and it actually improves overnight. Cook the base through the mashing step up to one day ahead, cool fully, and refrigerate in an airtight container. Hold the cheese, milk, cream, and fresh herbs until you reheat so the dairy does not separate. Reheat gently over medium-low and add the cheese off the heat.

Why did my potato soup turn out grainy?

Grainy texture almost always comes from pre-shredded bagged cheese, which has anti-caking agents, or from boiling the dairy. Grate cheddar fresh from a block and never let the soup boil once cream is added. If it already happened, blend briefly with an immersion blender and add warm broth to smooth the body.

What potatoes work best for potato soup?

Yukon Golds are ideal because they balance starch and moisture, breaking down just enough to thicken naturally without turning gluey. Russets make a thicker soup but need careful mashing. Red potatoes hold their shape well but will not thicken the broth on their own.

Can I freeze leftover potato soup?

Yes, up to 2 months in a freezer-safe container with 1 inch of headspace. Dairy soups can separate during freezing, so stir vigorously while reheating on the stovetop over low heat. Add a splash of milk or broth to restore the creamy texture.

What's a good fall side dish for this soup?

A crisp side balances the creamy body beautifully. My crispy Parmesan cauliflower bites work perfectly for fall dinners, and a simple green salad with apple cider vinaigrette also cuts the richness. For a heartier meal, serve with crusty sourdough for dipping.
